长江经济带城市全要素能源效率测度及影响因素研究:基于Super-MSBM模型

Research on the Measurement of Total Energy Efficiency and Its Influencing Factors in the Yangtze River Economic Belt:Based on Super-MSBM Model

基于Super-MSBM模型测度全要素能源效率,建立长江经济带城市全要素能源效率静态和动态空间模型,选取长江经济带100个地级及以上城市近二十年(1997-2016年)的样本,研究了长江经济带城市全要素能源效率的时空收敛性、差异及演变趋势。结果表明,长江经济带城市全要素能源效率整体呈下降态势,地区间全要素能源效率差异呈不断扩大趋势。产业集聚对长江经济带本地全要素能源效率的门槛效应显著;产业集聚对邻近地区的空间溢出效应亦会随着集聚水平发生改变。

This paper measures the total factor energy efficiency based on the Super-SBM(Super-MSBM)model,and establishes the static and dynamic space model of the total factor energy efficiency of the Yangtze River Economic Belt,We select a sample of 100 cities of the prefecture level and above in the past 20 years(1997-2016)to study time-space convergence,spatial difference and the time evolution trend of the total factor energy efficiency of the Yangtze River Economic Belt.The results show that the overall energy efficiency level of the Yangtze River Economic Belt is generally declining,and the difference in total factor energy efficiency between regions is expanding.The industrial agglomeration of the Yangtze River Economic Belt has a very significant local effect and threshold effect on local total factor energy efficiency.As the level of agglomeration increases,the spatial spillover effect of industrial agglomeration on neighboring areas becomes more and more significant.
